Williams undergoing MRI

WR Roy Williams is undergoing an MRI this morning to determine if there’s any ligament damage to his injured left shoulder, DallasCowboys.com reports

X-rays to his shoulder and collarbone were negative, according to the Web site.

Williams suffered the injury during Thursday night’s open practice at Cowboys Stadium. After colliding with CB Orlando Scandrick, Williams stayed on the field longer than usual. He went to the locker room after being examined by athletic trainers, shouting angrily while walking off the field.

There is no media availability today, but the Cowboys are expected to release an update on Williams condition. It’s likely he will not play in Saturday night’s preseason game against San Francisco.
